To increase the granulation rate of the disc granulator, the following aspects can be considered:

1. Optimize equipment parameters: The inclination Angle and rotational speed of the disc are key factors affecting the granulation rate. By adjusting these parameters, the movement trajectory and residence time of the materials within the disc can be controlled, thereby increasing the granulation rate.

2. Control the characteristics of raw materials: The moisture content of raw materials has a significant impact on the granulation rate. It is generally recommended to control the moisture content of raw materials between 10% and 15% to ensure that the materials have good adhesion properties. Ensure that the particle size of the materials entering the disc granulator is uniform to avoid uneven granulation due to excessive differences in particle size.

3. Process flow optimization: Before entering the disc granulator, the raw materials are pre-treated to enhance the uniformity of the materials and the granulation rate. Maintain a stable feeding speed to avoid fluctuations in granulation rate caused by uneven feeding.

4. Equipment maintenance and Inspection: Regularly inspect and maintain the key components of the disc granulator, such as the spray device, discs, and scrapers, to ensure that the equipment is in good condition. Regularly clean the interior of the disc granulator to prevent material residue and caking, which may affect the granulation effect.

5. Operation and Monitoring: Install an organic fertilizer equipment monitoring system to monitor the equipment's operating parameters in real time, such as disc speed and water spray volume, and make timely adjustments to ensure the best granulation effect. Regularly analyze production data, optimize process parameters, and increase granulation rate.

6. Use of additives: Adding an appropriate amount of binders, such as bentonite or humic acid, to the raw materials can enhance the viscosity and granulation rate of the materials.

Through the above measures, the granulation rate of the disc granulator can be effectively increased, and the production efficiency and product quality of the organic fertilizer production line can be improved.
